2 Claims.

This invention relates to sights for firearms and more particularly to the rear sights for rifles.

The purpose of my present invention is to provide a firearm sight of new and improved conthe outer surfaces of the two legs l2 so that loosening the cap screw in obvious manner allows the whole bracket 9 to be adjusted vertically to the desired position for setting the sight for the struction and particularly to provide a sight desired range. Preferably the outer end of the 5 device that is economical and simple in construchead of the cap screw is enlarged and knurled so tion, readily assembled and attached to a rifle that it can be operated by the finger and thumb. and not liable to get out of order nor be damaged Conveniently also the head of the cap screw may in use; and which has convenient and practicable be provided with a slot which will receive a screw adjustments for windage, range and size of peep driver or more often the edge of a coin. 10 hole in the sight, any one of which adjustments 'To aid in setting the sight for the desired can be changed by hand without affecting the range by this elevation of the standard [0 a series other adjustments. of spaced marks or notches l6 are provided upon Further advantages and purposes will appear the outer face of one of the legs l2, over or from the description herein. against which marks is located a pointer ll pro- 15 Fig. 1 is a side elevation of a firearm sight emjecting from a thin metal disk l8 which is held bodying this invention as seen from the left in position between the inner face of the head of hand side of a rifle of which only the adjacent the cap sc l5 the Outer face of t e s rear part of the receiver or equivalent part is I2 by the shank of said cap screw going through 2 shown. a hole in the middle of said disk.

In the portion of this flange is preferably knurled so as to a ow the notch between the legs l2 there is provided in ey p to be rotated between e fi er and the receiver a horizontally disposed threaded hole thumb as said eye cup with its forwardly disinto which fits the inner threaded end of a large posed extension 24 forms a cap screw for deheaded cap screw I5 the head of which engages tachably and adjustably holding the said eye 55 cup in place upon the cross arm by the engagement of the said extension with the thread of the nut 23, it being understood that the forwardly facing surface 2! on the said eye cup rests against the rear face of the cross arm above and below its elongated slot. Preferably this surface 2'! is provided on the front of a hub-like part 28 formed at the front of the eye cup and having about the same diameter as the vertical width of the cross arm 20 while the diameter of the eye cup proper is considerably greater than the said vertical width of the cross arm. This arrangement spaces the knurled flange on the eye cup slightly to the rear of the cross arm for greater convenience in adjusting the eye cup relative to the cross arm. By loosening the eye cup slightly relative to the nut 23 it will be seen that the eye cup can be shifted laterally of the fire arm viz. longitudinally of and along the said cross arm. For convenience in setting the eye cup to the desired position transversely of the fire arm by such adjustment there are provided a co-operating set of marks upon the upper face of the nut 23 and the upper face of the cross arm 20. These marks may conveniently consist of one cross mark 29 in the top surface of the nut 23 immediately above the axial center of said nut. On the upper edge of the cross arm there is provided a series of cross marks or small notches 30. Jn this way the user of the fire arm equipped with such a sight can adjust the sight to the desired amount for windage.

The eye cup is provided with a sight aperture 3| which is placed at the center of the eye cup and extends axially through the eye cup proper, its hub 28 and its forward extension 24. Pivotally mounted upon the rear face of the eye cup and within the recesses formed by the flange 26 there is provided the sight plate 32. This sight plate has a plurality of spaced, different sized sight openings as 33, 34 and 35. The sight plate is formed of spring metal as thin sheet metal, so formed and tensioned that when the said sight plate is pivotally fastened to the eye cup by the pivot screw 36 having its shank extend through a hole 31 in the sight plate into a suitable hole in the eye cup at a point remote from the central sight opening of said eye cup, the said sight plate will be yieldingly pressed against the rear face of the eye cup. As appears from the drawing the sight plate may conveniently be in the form of a heart-shaped or roughly triangular shaped piece of metal with the pivot hole 31 near the point of the heart and the different sized sight openings 33, 34 and 35 are in the middle portion of said plate spaced apart from each other and each one spaced from the pivot hole of said plate the same distance as the axis of said pivot screw 36 is from the center of the sight aperture or practically the axial center of the eye cup. It will then be obvious that by swinging the said sight Plate any one of the said sight openings in the sight plate may be brought to register with the sight aperture through the eye cup. Suitable integral means are provided on the said sight plate and eye cup to hold the said plate selectively with any of the sight openings in registering position by the spring tension of said sight plate. Such means may consist of a small forwardly extending projection 38 provided upon the sight plate which will extend into any one of three small recesses 39 provided in the rear face of the eye cup. These recesses are a similar distance from the axis of the pivot screw 31 as is the projection 38 and they are so spaced across the rear face of the eye cup that the different ones are engaged by said projection when the sight Plate is swung to have its sight openings in registering position with the central axis of the eye cup. Conveniently a rearwardly extending car 40 is provided upon the edge of the sight plate at a point remote from the pivot screw 36 so that the user can readily swing the sight plate to its different positions by pushing said ear with the nail of a finger or thumb.

It will now be seen that the sight plate may be moved back and forth to any of its desired positions without interferring with the vertical adjustment of the sight device as a whole for range and without interfering in any way with the lateral adjustment of the eye cup for Windage. Also it will be seen that either of those adjustments can be made without disturbing the other and without disturbing the adjustment of the sight plate upon the eye cup.

In the drawing the eye cup is illustrated in a position where the movable sight plate is in upright or vertical position as a whole when its central sight opening is being used and this is a convenient arrangement of the parts. It will be noticed however that if through variation in the manufacture. or through wear of parts the eye cup will come to a tight position relative to the cross arm when the pivoting screw of the eye cup and the sight aperture of the eye cup are not in a vertical plane, there will be no interference with the manipulation of the sight plate. The sight plate can be swung to any of its positions no matter what the relative position of the pivot screw may be to the central sight aperture of the eye cup.

What I claim as new and desire to secure by Letters Patent is:

1. In a firearm sight, the combination of an attanhing-bracket having a cross arm located above the firearm and extending transversely thereof and having a slot therethrough, .an eye cup mounted to the rear of said cross arm and having at its front side a centrally disposed, externally threaded extension projecting through the slot in said arm, said eye cup having a centrally located sight aperture extending through the eye cup and its extension, a nut engaging said eye cup extension and said cross arm for detachably holding the eye cup in place, a spring metal sight plate pivotally mounted on the rear face of the eye cup by a pivot spaced from the sight aperture, said plate having a plurality of different sized sight openings adapted to be selectively brought into line with the sight aperture in the eye cup by swinging said plate, and cooperating indentations and projections on the interengaging faces of said eye cup and sight plate for yieldingly holding the plate in adjusted position by the spring tension of said plate.

2. In a firearm sight, the combination of an attaching bracket having a cross arm located above the firearm and extending transversely thereof .and having a horizontally elongated slot therethrough, an eye cup mounted to the rear of said cross arm and having at its front side a centrally disposed, externally threaded extension projecting through the slot in said arm, said eye cup having a centrally located sight aperture extending through the eye cup and its extension, a nut threaded on said eye cup extension and engaging the front of said cross arm for adjustably holding the eye cup in place along said cross arm, a spring metal sight plate pivotally mounted as] GEOMETRECAL msinumme amid? 0m on the rear face of the eye cup by a pivot spaced on the interengaging faces of said eye cup and from the sight aperture, said plate having a plusight plate for yieldingly holding the plate in adrality of difierent sized sight openings adapted justed position by the spring tension of said to be selectively brought into line with the sight plate.
